24/25 Physics Midterm Review

Front

What is the acceleration due to gravity on Earth?

Back

-9.8 m/s², which is the same at all positions regardless of height.

Front

What are significant digits in a measurement?

Back

All known digits plus one estimated digit.

Front

What is a dependent variable?

Back

The variable being tested, counted, or measured that responds to the independent variable.

Front

What factors contribute to the potential energy of an object?

Back

Height above the Earth's surface, mass of the object, and gravitational constant (g). Velocity does not contribute.

Front

What does Newton's law of inertia state?

Back

An object at rest stays at rest, and an object in motion stays in motion unless acted upon by a net external force.

Front

What is potential energy?

Back

The energy stored in an object due to its position or configuration.

Front

What is kinetic energy?

Back

The energy of an object due to its motion, calculated as KE = 1/2 mv².

Front

What is the formula for calculating force?

Back

Force (F) = mass (m) × acceleration (a).

Front

What is the difference between independent and dependent variables?

Back

The independent variable is manipulated to observe its effect on the dependent variable.

Front

What is the principle of conservation of energy?

Back

Energy cannot be created or destroyed, only transformed from one form to another.
